The HP/Agilent 83623A Synthesized Sweeper generates RF and microwave signals from 10 MHz to 20 GHz with synthesized accuracy and sweep capability. Delivering +17 dBm maximum output power with -76 dBc phase noise at 20 GHz (10 kHz offset), it serves as a primary signal source for component test, receiver characterization, and frequency conversion applications. The instrument combines multiple modulation modes—pulse, amplitude, and frequency—with flexible sweep patterns and remote control via HP-IB, making it suitable for both bench testing and integrated test systems.
